Subject: [PATCH v3 03/16] arm64: sysreg: Add layout for ICH_MISR_EL2
Date: Thu, 6 Feb 2025 15:49:12 +0000 [thread overview]
Message-ID: <20250206154925.1109065-4-maz@kernel.org> (raw)
In-Reply-To: <20250206154925.1109065-1-maz@kernel.org>
The ICH_MISR_EL2-related macros are missing a number of status
bits that we are about to handle. Take this opportunity to fully
describe the layout of that register as part of the automatic
generation infrastructure.
